SU carburettors, what you should know before tuning

This video is a follow on of the previous video where we captured the carb performance during a test ride. In this video I take you through the SU workings, the adjustment area's and an explanation on what is possible to tune and adjust. We then look at the AFR map/graph of the previous ride and identify what the carburettor must have done. Once all that is done we will rebuild the carb in another video and then tune it in full. That will be the last video
